C++ :: Multimap Alphabetically Ordering With Char
Jan 18, 2015I understand multimaps are key ordered. I have no problems with ints but when I put my char arrays in they are not alphabetically ordered. I must use char array and not <string>. Is it possible to alphabetically order them with char*
39 int c;
40 User *user;
41 char nameH[200];
42 char line[200];
43 int ageH;
44 double wH;

C :: Shared Memory / Cannot Read Last Element In A Struct
Jun 27, 2014I have trouble reading the last element in a struct.I do get the correct value for the first two elements. In my example that is:
a = 11 and c = H
however I get:
b = 0
but I am expecting b=2
I got two files to handle this.The first one is writing data to memory -
Code:
#include <sys/shm.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
}
[code]....
why I cannot get correct value for the third element in my struct?In the second file where I'm reading from memory I allocate some space. Is this incorrect in some way? I'm running this on a Linux machine.
C++ :: Periodic Table - Char Element?
Mar 11, 2013Here is the code

let's say someone puts in h and Hydrogen comes up, and when someone puts in he, hydrogen also comes up, what am i doing wrong.
C :: Unable To Display Element Of Char String?
Mar 2, 2013Why I cannot do this to display each element of my char string? What is the proper way?

C :: Set Variable Of Type Char Equal To Element In Array Of Characters
Mar 3, 2014I am trying to set a variable of type char equal to an element in an array of characters. For example:
char data[4] = "x+1";
char element;
element = data[2];
This seems like a logical progression from number arrays, but when I print both element and data[2], I get data[2] as expected, but element gives a different character every time (I assume a garbage value).

Jan 3, 2015I am trying to save 5 persons names to a struct, and then printing them afterwards, shortly before the program ends. I tried to print the char string out right after it has been copied over, and it showed fine, but when i try to write it out right at the end of the program (its in a separate function) the terminal just prints gibberish.
the function looks like this:
Code:
int printUser(){
printf("Following patients have been recorded in this session:
");
struct database patient1;
struct database patient2;
struct database patient3;
[Code]...
the output looks like this(as you can se in under structest, that it shows the correct string, it also uses printf):
C++ :: Using Struct / Char Array For Tic Tac Toe Game
Feb 11, 2014I basically just want a function that tells me if 'X' or 'O' won in a tic-tac-toe game. I don't care about the visuals, I just want a function that tells me if 'X' or 'O' won. If X wins, return 0. If Y wins, return 1.
How to do the diagonals, but as far as the across and down wins, I know I have to use a nested for loop, but am a little stuck, as to exactly how to set it up.

C++ :: Error On Assigning New Char Value From Struct
Feb 17, 2015Well I tried to assign a new char value from a struct to another char variable but I got the "Cannot convert 'int' to 'char'" error when compiling. I've tried several alternations but I still can't get away with this error.
Here's a section of the code:

View 2 Replies View RelatedC++ :: Ordering A Map By Value
Jan 22, 2015So I have a map of the form:
std::map<std::string, int> m;
I want to order this by its int value, but I don't know how to write such a function. I've had two attempts thus far:
One by using std::pair, as a map consists of pairs.
bool cmp(std::pair<std::string, int> p1, std::pair<std::string, int> p2) {
return p1.second < p2.second;
}
The other by trying to use maps, which seemed off to me at first, but I still tried it out (obviously it didn't work):
bool cmp(std::map<std::string, int> m1, std::map<std::string, int> m2) {
return m1.begin()->second < m2.begin()->second;
}
How do I write a function that compares the values of a map such that I can use it to sort the map?

Aug 2, 2014Here's the objective of the program: "Instead of using ABCDEFGHIJ to order letters use DCBAJIHGF go order. The program should determine which 4-letter word is larger of two based on this new ordering system."
Not even sure how to start with this problem , how would I go about defining my own ordering system?
C# :: Ordering Of Embedded Resources
Oct 14, 2014I have 10 or so .sql scripts (the number is likely to rise) which are required to be kept with a C# application.
For the most part the embedded resources seem to work fine , however I require a way in which to guarantee the ordering in which the files are run.
What I do currently:
Retrieve the details of the embedded resources using : Assembly.GetManifestResourceNames()
(and a bit of linq to filter based upon my requirements) which I pass to a list, I then later on use the list to grab the physical resource when its needed.
The files are named such as:
1_ScriptDescription.sql
2_ScriptDescription.sql
3_ScriptDescription.sql
10_ScriptDescription.sql <--- Here's my problem! This will come after 1_ScriptDescription.sql
Ideally I need a way in which to order the list or some kind of ordering when I pull from
Assembly.GetManifestResourceNames()
But I'm not really sure of a practical way to do this, I did consider manipulating the string .....
C :: Byte Ordering In Binary Buffer
Apr 13, 2014Basically it has to do with the byte ordering in a binary buffer vs the typing of a variable used to hold it.
To give you an example, if I have a buffer (say of indefinite length), and a ptr "ptr" pointing to a byte in the buffer (say, C0), such that if I open the buffer in a binary viewer it reads like this: Code: C0 DD FE 1F Such that this is true:
Code:
/*ptr is uint8_t*/
*ptr == 0xC0
Then I do this:
Code:
uint16_t var;
var = *(ptr+1);
I would expect the result to be:
Code: DD FE /*56830*/
Though if I print that out with:
Code:
printf("%u
", var);
It'll print:
Code: 65245 /*(FE DD)*/
Now obviously it's byte swapped, but what is causing that? I'm assuming if I just stream that out to a file byte by byte it'll be fine, so it's something with the 16 bit data type (also have seen this issue with a 32 bit data type, where all 4 are in reverse order). Is there any way to 'fix' it except bit shifts & masks?
C++ :: Array In Class - Set With A Special Ordering
May 24, 2013I have an array in a class with some numbers in a specific order. Now I want to create a set with references to that array ordered after the arrays content. I thought a solution could be something like
class Holder {
int o[10]= {1,5,7,2,3,8,4,9,6,0};
public:
set<int,my_order> m_s;
Holder() {
for(int i=0; i<10;i++) {
m_s.insert(i);

How to create the my_order.
C/C++ :: Ordering Array From Largest To Smallest?
May 25, 2014Write a program that reads in a list of integers into an array with base type of int. Provide the facility to either read this array from the keyboard or from a file, at the user's option. If the user chooses file input the program should request a file name. You may assume that there are fewer than 50 entries in the array. Your program determines how many entries there are. The output is to be a two-column list. The first column is a list of the distinct array elements; the second column is the count of the number of occurrences of each element. The list should be sorted on entries in the first column, largest to smallest.
For example, for the input
-12 3 -12 4 1 1 -12 1 -1 1 2 3 4 2 3 -12
the output should be
N Count
4 2
3 3
2 2
1 4
-1 1
-12 4
Here's My code So far:
#include <iostream>
#include <fstream>
using namespace std;
const int SIZE = 50;
[Code]....
My Code outputs the numbers From Largest to Smallest according to given array, but I need to make it to output the numbers once(if its repeated)
C :: Save Values From A Char Buffer Into Integer Values Of A Struct?
Jul 3, 2013I'm attempting to save values from a char buffer into integer values of a struct.
This is what resides in the buffer "STD 2 2 2 2 2 2 2 " and this is my sscanf call
Code:
sscanf(buffer, "STD %d %d %d %d %d %d %d
", &dt_struct.date,
&dt_struct.mth,
&dt_struct.year,
&dt_struct.dow,
&dt_struct.hr,
&dt_struct.min,
&dt_struct.sec);
I then print the values back out in a string using sprintf.
Code:
sprintf(t_string, "STD %d %d %d %d %d %d %d
", dt_struct.date,
dt_struct.mth,
dt_struct.year,
dt_struct.dow,
dt_struct.hr,
dt_struct.min,
dt_struct.sec);
But this is what I get:
STD 0 0 2 0 0 0 2
Instead of what I want:
STD 2 2 2 2 2 2 2
C :: Parsing Char Array To Array Of Struct To Process Packets
May 28, 2013I wrote this simplified version of a program i am writing that parses data in UDP packets. In the process of doing so i pretty much answered all my questions and fix all the problems i was having.
decodeSystemMap function will be in loop, and will proccess packets that have mostly the same data, only a few items will be added or changed or deleted.
whats the best way to check if there are any new, deleted, or removed items in the packet and only modify those?
Is there anything unsafe / dangrous about the way the code is now?

View 4 Replies View RelatedC :: Last Element Of List Overwritten By First Element Of Another
Feb 23, 2013I have a global list that contains smaller lists of char arrays. I have an issue where when I'm reading back the inner lists the last element of one list seems to point to first element of the next.
So my data looks like the below (values separated by commas with the pairs separated by tabs. The last pair in a line is the same as the first). When I read the first list back instead of seeing "456.678,678.98" as the last element in the list. I see "435.67,234.98" twice: at the end of the first list and start of the other. I have debugged when the list is populated and can see the correct values going in so I can't figure what's happening.
456.678,678.98 123.45,345.56 256.67,789.98 456.678,678.98
435.67,234.98 123.65,342.56 987.78,678.34 435.67,234.98

obstacle_list = op_prg_list_create();
while (fgets(line, sizeof(line), obstaclePositions_traj_file) ) {
token = strtok(line, "
"); //Pull the string apart into tokens using the
